The W3C XML Protocol WG held a teleconference on 25 October 2000. The
meeting began at 8:00a PDT.
AGENDA
1. Roll call, assign scribe (5 minutes) (6 minutes)
2. Agenda review, call for AOB (5 minutes) (4 minutes)
3. Approval of minutes from last week (accept DavidO's change? [1]) (5
minutes) (2 minutes)
f2f minutes updates have already been posted. They will be
incorporated.
5. Response to XML Schema, see [2] (5 minutes) (7 minutes)
Schema WG looking to create libraries of types and is soliciting XP
collaboration. What is the XP group's response to this?
HenrikFN: in general yes. what's not clear is what is the context and
timeline and deliverables? how to deal with dependencies?
PaulC: this overlaps with data representation, PC will take on XP
representation on these issues.
Some agreement that it would be good for Schema to define a type
library, and for XP to transfer our types to that activity.
ACTION: DavidF: will draft a reply saying it's a good idea, it's
early, more specifics needed, and that PaulC will represent XP in
any collaboration with the schema WG.
